Fifty years ago today I was eight years old, and it was a summer day in Concord, Massachusetts. I have vague memories of watching the moon landing on our black-and-white television set. But did we watch it while it was happening, or did we watch it on the news later on? I think we watched on the news later in the day.
What I do remember is that it was a big topic of conversation among kids my age. Kids in my neighborhood also talked about how we were going to have to leave Alcott school and go to a new school in the fall. We probably also talked about the new split in the American League between the East and West divisions, and my hero Jim Longborn was still pitching for the Red Sox. But the moon landing had the biggest impact on my imagination, by far.
In fact, it would be hard to overestimate the impact the moon landing had on my imagination. I was so sure there would be regular travel to the moon by the year 2000. When I studied physics in college and understood how much energy it takes to lift humans out of earth’s gravity well, regular travel to the moon began to seem far less probable.
These days I am far more cynical. Before I get excited about moon travel, I want to know where the energy is going to come from, and what the carbon footprint of moon travel will be. These days, I’m more interested in how we might reduce carbon in the atmosphere, to lessen the impact of global climate change. Which means that I’m far more interested in the Trillion Tree Campaign that perhaps “could capture 25% of global annual carbon emissions.” I guess you could say that self interest has prompted a greater interest in ecological science than in astronomy or astrophysics.
